使用.serializeArray()获取数组格式的数据，然后将其转换为对象:

function getFormObj(formId) {
    var formObj = {};
    var inputs = $('#'+formId).serializeArray();
    $.each(inputs, function (i, input) {
        formObj[input.name] = input.value;
    });
    return formObj;
}

如果您正在使用jQuery，这里有一个小函数可以做您正在寻找的事情。

首先，添加一个ID到你的表单(除非它是页面上唯一的表单，然后你可以只使用'form'作为dom查询)

<form id="some-form">
 <input type="radio" name="foo" value="1" checked="checked" />
 <input type="radio" name="foo" value="0" />
 <input name="bar" value="xxx" />
 <select name="this">
  <option value="hi" selected="selected">Hi</option>
  <option value="ho">Ho</option>
</form>

<script>
//read in a form's data and convert it to a key:value object
function getFormData(dom_query){
    var out = {};
    var s_data = $(dom_query).serializeArray();
    //transform into simple data/value object
    for(var i = 0; i<s_data.length; i++){
        var record = s_data[i];
        out[record.name] = record.value;
    }
    return out;
}

console.log(getFormData('#some-form'));
</script>

输出如下所示:

{
 "foo": "1",
 "bar": "xxx",
 "this": "hi"
}

我用这个:

jQuery插件

(function($){
  $.fn.getFormData = function(){
    var data = {};
    var dataArray = $(this).serializeArray();
    for(var i=0;i<dataArray.length;i++){
      data[dataArray[i].name] = dataArray[i].value;
    }
    return data;
  }
})(jQuery);

HTML表单

<form id='myform'>
  <input name='myVar1' />
  <input name='myVar2' />
</form>

获取数据

var myData = $("#myForm").getFormData();

我已经包括答案，也给回所需的对象。

function getFormData(form) {
var rawJson = form.serializeArray();
var model = {};

$.map(rawJson, function (n, i) {
    model[n['name']] = n['value'];
});

return model;
}

你也可以使用FormData对象;FormData对象允许您编译一组键/值对，以便使用XMLHttpRequest发送。它主要用于发送表单数据，但也可以独立于表单用于传输键控数据。

        var formElement = document.getElementById("myform_id");
        var formData = new FormData(formElement);
        console.log(formData);

这是我的香草JS版本(在Chrome上测试)

适用于:

name = "输入" Name ="form[Name]"(创建一个对象) Name ="checkbox[]"(创建一个数组对象) Name ="form[checkbox][]"(创建一个数组) Name ="form[select][Name]"(创建一个只包含所选值的对象)

/**
